"The plan for the Trump campaign for this convention is to help the American people understand more about Donald Trump the man, not just the candidate they see on the campaign trail," Manafort said in a news conference Sunday.

"This is a Trump convention," he said, adding that the presumptive presidential nominee will make several appearances during the convention.

Plans on who will formally introduce and nominate Trump will be released on Monday, the first day of the convention, he said.
